摘　　要：通过对上海市区园林绿地29个样方的植被结构与微环境及土壤湿度、温度的调查,结果表明,绿地具有明显的增湿降温作用,影响这一作用的主要因素是绿地的乔木植物盖度。土壤湿度与草本植物盖度呈极显著正相关。土壤湿度、温度在一定区间内,呈极显著正相关。复杂完善的植被结构对防止土壤水分蒸发具有较好的效果。By analyzing the vegetation structure and temperature and moisture for soil and microclimate of 29 urban green spaces in Shanghai, we found that the green spaces can sufficiently reduce the air temperature and increase the moisture, mainly due to the arbor coverage of green spaces. The correlation was found between soil moisture and herbage coverage was significant. Significant correlation was found between soil temperature and moisture within a certain range. The vegetation with multiple structures had better effect on preventing soil evaporation.
